[Live-devel] RTCPInstance error: Hit limit when reading incoming packet over TCP. Increase "maxRTCPPacketSize"

[Caio Klein]

Ross,

Thanks for the answer, but this sounds like a vulnerability. If any of the
system clients (VLC) or sources (cameras) has a buggy code, they may bring
the live555ProxyServer down.

what is required to make the proxyserver code immune to this kind of
external bugs?

Thanks,

Caio
